Figure 5. SAH-binding site of BthII1283.

Stereoview (left) and schematic (right) representation of interactions of SAH (balls and sticks) with residues of the Class I methyltransferase fold (light blue) and N-teminal extension (salmon). Dashed lines represent potential hydrogen bonds. Water molecules are shown as red spheres in the stereo diagram and ‘W’ in the schematic drawing.
